1. Add an image view in your initial view controller as-UIImageView *animatedSplashScreen;

2. Set its frame in such a way that its compatible with all the devices as
animatedSplashScreen  = [[UIImageView alloc]initWithFrame:[[UIScreen mainScreen]bounds]];

3.Add this image view to your main view by adding it as a sub view as-
[self.view addSubview:animatedSplashScreen];

4. Create an array which contains those sequence of images,for example you have to animate then u need to have a set of images which contains text as 1.Hello 2.Hello this 3.Hello this is 4.Hello this is animated 5.Hello this is animated splash.

5. Now we will create two functions-One in which we simply add the images to the array,set animation repeat count,set Animation duration & the other function to simply stop animation & remove the animated sub views from the main view u can check it below.

-(void)functionOne{
    animatedSplashScreen.animationImages= [NSArray arrayWithObjects:[UIImage imageNamed:@"bolt1.png"],[UIImage imageNamed:@"bolt2.png"],[UIImage imageNamed:@"bolt3.png"],[UIImage imageNamed:@"bolt4.png"],[UIImage imageNamed:@"bolt5.png"], nil];
    animatedSplashScreen.animationRepeatCount=1;
    
    
    animatedSplashScreen.animationDuration=5;
    
    animatedSplashScreen.animationRepeatCount=1;
    animatedSplashScreen.animationDuration=5;
    [animatedSplashScreen startAnimating];

    [self performSelector:@selector(hideSplash:) withObject:animatedSplashScreen afterDelay:5.0];

}

Hiding splash here-

-(void)hideSplash:(id)object
{
    UIImageView *animatedImageview = (UIImageView *)object;
    [animatedImageview removeFromSuperview];
}
